Our fearless leader. He makes sure we have direction, money, baked goods, and mentorship. He gets really excited about science, running, education, and Twitter. But mostly about science.



Dr. Parisi is a senior scientist in the Mosca Lab. He received his B.S. from SUNY Purchase and then his M.S. and Ph.D. degrees from New York University. He has done postdoctoral fellowships at Duke University and the NIH working on various aspects of Drosophila biology, genetics, and neuroscience. Before coming to Jefferson, he was a research specialist at the University of Pennsylvania. He brings over 20 years of Drosophila experience to the lab and will use that to help advance our projects on neurodevelopment and synaptic organization!


Postdoctoral fellow
Stephen Tymanskyj, Ph.D.

Steve is currently a joint postdoc between the Mosca Lab and the Ma Lab here at Jefferson. He received his B.S. in Pharmacology from the University of Newcastle upon Tyne and completed his Ph.D. at King’s College London in the Gordon-Weeks Lab studying MAP1B phosphorylation. Steve brings his expertise in cytoskeletal biology and live imaging to the lab to better understand synaptic organization and designing new tools and technologies for imaging synapses in vivo.


Graduate Student
Michael Aimino, B.S.

Mike is a graduate student in the Graduate Program in Neuroscience. He received his B.S. in Neuroscience from Dickinson College. Prior to Jefferson, he was a clinical research assistant at Penn and a technologist at Penn State Hershey studying alcohol addiction and stress in mice. Mike studies cell surface proteins in synaptic development and is currently spearheading the charge for a lab dog. 


Graduate Student
Alison DePew, B.S.

Alison is a graduate student in the Graduate Program in Neuroscience. She received her B.S. in Neuroscience from the University of Scranton studying facial features and schizotypal personality traits. She also studied Drosophila ovulation at UConn and brings her fly experience to Jefferson. She studies olfactory behavior and synaptic organization and holds the official title of our first permanent graduate student.


master’s Student
elizabeth moese, b.A.

Libby is a Master’s Student in Biomedical Science at Thomas Jefferson University. She comes to us from Miami University where she received a B.A. in Psychology and studied fear memory destabilization in rats. She’s new to Drosophila but will be studying retrograde mechanisms of synapse formation and synapse maturation in the lab.


Research technician
Lucas restrepo, b.s.

Lucas joins our lab after completing his B.S. in Biology from The Catholic University of America. There, he worked on yeast ABC transporters with Dr. John Golin. He keeps the lab running in tip-top shape, ensures the flies are well fed, and is helping us push back the frontiers of knowledge on multiple projects studying larval and adult synapses. Lucas is also a die-hard Eagles fan who #truststheprocess.

We're always looking for talented, driven scientists to join us in the continuing fight to push back the frontiers of knowledge.



Let’s face it. We’re mildly obsessed with Gritty. And who wouldn’t be? He(?)/She(?)/It(?)/They(?) are amazing. They are immortal. They came in like a wrecking ball, and they made Philly love them. Then they made the world love them. We consider Gritty an unofficial lab member.
